A few points you've made here:
1. The fact that you don't find Crossfit interesting is totally reasonable, and a very important point for anyone looking to get into working out. As the saying goes, the most effective training program is the one you actually stick to. If you don't enjoy something, you'll never stick with it, and you'll never see long-term results. That being said, this is a very subjective criteria. The fact that you don't find the Crossfit style of training interesting means it isn't for you, but it's hard to apply that to anyone else.
2. In spite of the rep Crossfit gets for being all about high-intensity-make-you-puke workouts, one of the core beliefs of the program is that it be sustainable over a lifetime. In fact, this is the point that gets stressed at coaching certifications more than any other. The loudest Crossfitters may be 25 year old frat-boy douches, but the program is designed to be inclusive, even for the de-conditioned and the elderly. This comes out of an understanding that functional movements (squats, deadlifts, presses), if performed with consistently good form, should almost never lead to injury, and out of a belief in infinite scaleability. The result is that you can run a 65 year-old grandmother through what is essentially the same workout as a 20 year-old college athlete. Will the intensity level be the same? Of course not, but the goal is only to maximize relative intensity in a safe, consistent manner. This in contrast to things like distance running - the most popular form of exercise in America - which injures something like a third of all participants annually.
3. I do want to second (third?) the comments about finding a good gym with quality coaching. As with anything, the coach matters more than the program. I've had the good fortune to workout at two of the best coached Crossfit gyms in the US, and have dropped into some pretty bad ones. Well-coached gyms focus on mechanics, then consistency, then intensity. They routinely hold athletes back from muscling through a workout with bad form. They run the classes like... well... classes, with actual teaching. In contrast, "bro" gyms with poor coaching focus almost exclusively on intensity, on increasing weights and decreasing times, and do very little teaching. They encourage athletes to push themselves beyond the point of safety, and as a result see a lot of preventable injuries.
One thing to think about when signing up for any program like this, whether it be Crossfit of boxing. Are you just looking for a space to workout on your own, or are you looking for coaching? If you want coaching, understand that having a coach is about having accountability. Sometimes your coach will tell you things you don't want to hear ("no more weight on the bar until you fix your back position," for instance.) This is a good thing. It keeps you safe and gets you stronger. Your coach is not your cheerleader.
